Abstract (en)
[origin: WO2014063990A1] The invention relates to a method for producing a soft token having the following steps: - provision of a secure element (172), wherein a protected memory area (186) of the secure element stores a secret key from a first asymmetric cryptographical key pair, - setup of a first cryptographically secured connection (180) between an electronic appliance (174) and a service computer system (150), - transmission of a request for production of the soft token from the electronic appliance to the service computer system via the first connection, - production of a one time password on the basis of reception of the request by the service computer system, - registration of the one time password as an identifier for the first connection by the service computer system, - transmission of the one time password from the service computer system to the electronic appliance via the first connection, - output of the one time password via a user interface (194) of the electronic appliance, - setup of a second cryptographically secured connection (182) between a user computer system (100) and the service computer system, - input of the one time password into the user computer system, - transmission of the input one time password from the user computer system to the service computer system via the second connection, - checking by the service computer system to determine whether the registered one time password matches the one time password received via the second connection, and, only if this is the case, reading of at least one attribute stored in an ID token (106), production of the soft token by signature of the at least one attribute and of the public key from the first cryptographical key pair, transmission of the soft token via the first connection to the electronic appliance and/or transmission of the soft token via the second connection to the user computer system.
